This commit upgrades the Linux kernel to 6.12.18 from 6.6.x, which comes
from the linux-yocto upstream.
The following changes we made to support the kernel upgrade.
For linux debian package deb_patches folder.
We adapt the kernel related patch for 6.12.18, and cherry pick the
following 8 commits to support to build the kernel 6.12.x.
1) commit f77deecbb5d4 "d/rules.real: Unset KBUILD_HOSTCFLAGS etc.

2) commit 0d0d62b7d1cc "d/rules.d/Makefile.inc: Add scripts/include to
header include path"
https://salsa.debian.org/kernel-team/linux/-/commit/0d0d62b7d1cc
3) commit 4ad01663251d "[x86] linux-cpupower: Update turbostat Makefile

For the Linux source code patches folder.
1) We adapt the patch 0001, 0003, 0005, 0006, 0010, 0014 and 0017 based
on kernel-6.12.18.
2) Remove all the ice port back patches because that has been included
in our source code.
For the kernel config.
We enable CONFIG_CPUSETS_V1 and CONFIG_MEMCG_V1 to fix install issue.
Verification:
- Build kernel and out of tree modules success for rt and std.
- Build iso success for rt and std.
- Install success onto a All-in-One lab with rt kernel, and can
switch to std kernel.
- Boot up successfully in the lab.
- The sanity testing was run and the test results PASS.
- The cyclictest benchmark was also run on the starlingx lab, the result
is "samples: 43199996 avg: 1656.295 std_dev: 67.617 max: 8827
99.9999th percentile: 8652“，It is worse than linux-6.6.x.
- The network performance test had been done. For TCP, better than
kernel-6.6.x, for UDP, a little worse than kernel-6.6.x, for STCP,
can not do the test that is same with kernel-6.6.x.
